JGoren, all: RE: CDMA security Here is a post from Clark... Message 8383583 Michael - I thought that the short code/ long code dance along with some other stuff did encrypt CDMA? The equivalents to the short codes and long codes in a military system would indeed be used to encrypt the system. But in CDMAOne there are two things that prevent it from being used as encryption: 1) The code sequence generation method is publicly known. 2) The sequence is only about 40 bits long. As has been shown many times, this is not long enough to prevent cracking pretty easily (not that cracking is even needed given item #1). Note that the big advantage to CDMA is its interference resistance, but this isn't really needed in point-to-point communications without much interference from neighbors, and this is the probable environment of the Cinecomm system. Clark hope this helps, dave
